Sampling techniques
|
Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.

Rock chip samples were collected at various locations within the company's granted tenements, specifically of pegmatite. Samples of approximately 1-1.5kg were collected, as multiple small fragments, from either outcrop or subcrop.

Aspects of the determination of mineralisation that are Material to the Public Report. In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.

1-1.5kg rock chip samples were collected from either outcrop, subcrop or float and placed inside individually uniquely numbered calico bags and secured. The bags were transported to Intertek Laboratories in Kalgoorlie, WA for sample preparation. Subsequent geochemical analysis was conducted by Intertek in Perth WA.
In the laboratory, samples are crushed and pulverized to produce an homogenous subsample for analysis via a 4 acid digestion/ICP-OES & ICP-MS (Intertek code 4A/OM20) for Ag,Al,As,Ba,Be,Bi,Ca,Cd,Ce,Co,Cr,Cs,Cu,

b,Sc,Se,Sm,Sn,Sr,Ta,Tb,Te,Th,Ti,Tl,Tm,U, V,W,Y,Yb,Zn and Zr. For Li results exceeding 5000ppm, are reanalyzed via sodium peroxide fusion and hydrochloric acid digestion in Teflon tubes and then analysed by ICP-MS
